GOLF-CLUB.

Specification of Letters Patent. I Patented M3 24 1e14,,

Application filed March 28, 1913. Serial No. 757,304. 7 4

'1 'o aw whom it may concern Be it known that I, JAMES MILLAR, a subject of the King of England, residing at Chicopee, in the county of Hampden, in the State of Massachusetts, have invented certain new and useful Improvements in Golf-Clubs, of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof.

This invention relates to golf clubs and has for an object particularly to improve the general construction of the heads thereof whereby the effective propelling force is increased without unduly. increasing the weight of the head and withoutdisturbing the balance of the club.

in further object is to provide a head for golf clubs in which may be secured removable weights readily interchangeable to vary the effective weight of the head as desired under different conditions of use. In accordance with the invention a plurality of of the golf club and are so disposed that their weight is directly behind the point of impact of the head with the ball at the instant the latter is struck.

The invention will be more particularly described hereinafter, reference being had now to the accompanying drawings in which Figure 1 is a fragmentary view in per spective of the head of a golf club embodying the present invention. Fig. 2 is a view in vertical section taken on the line 2-2 of Fig. 1 and looking in the direction of the arrows and showing one arrangement for securing the weights in place. Fig' 3 is a view similar to Fig. 2 showmg a modified construction for securing the weights in place.

The head a of the club designated generally by the reference character I), has its front and rear faces a and a countersunk to receive weighty blocks oand (l of any desired outline, but adapted to fit snugly within the corresponding recesses above referred to. The weight 0 which is disposed in the striking face a of the head maybe of relatively great area so as to constitute the striking surface of the club. The weight 62 which is disposed in the rear side of the head a, however, is preferably of relatively small cross sectional area so that its effective weight will be more nearly concentrated along the studs 0" or d which serve to connect the weights 0 and "d as will appear, and which are coaxially disposed with respect to said weights. In Fig. 2 it will be noted that the stud c is formed integralv with the front or striking weight c and is threaded at its rear end, as at 0 to receive thereon the correspondingly threaded weight (Z, the latter being provided with grooves 55 in its rear face to receive a suitable too]. to

facilitate the screwing of the weight a? on the stud c. The striking weight 0 is prefer; ably provided on its rear face with lugs c which rest in corresponding recesses formed in the head a so that movement of the wei ht c about its axis isprevented positively. T is construction, it will be appreciated, is of importance when the weights are being secured. in place;

.In assembling the head a and its constituent parts, after the head a has been properly bored through to receive the stud 0 and its front and rear faces countersunk to receive the weights 0 and (Z respectively, the weight 0 is placed. in its recess with the lugs 0 in engagement with their corresponding re cesses. At this time, the stud 0' may project somewhat beyond the rear face of the head,

The weight 03 may then be threaded on to the stud 0' until its inner end abuts against the bottom of its recess. By proper machining the striking weight 0, the rear face of the weight d and the stud 0 may all he finished to lieflush with the contiguous faces of the head a'so that the exposed surface of the latter shall be contiguous and symmetrical.

The exposed face of the striking weight 0 may be finished in any approved form to provide a suitable frictional engagement be tween the surface thereof and the ball.

By the constructiondescribed, it will be.

flight of the ball, that is, the weig t of the blocks is transmitted through the s ud to a:

point directly behind the point of impact of the head with the ball. This insures a maxi mum propelling force behind the ball and so increases generally the eificiency of the club. By disposing one weight adjacent the striking face of the club and the other weight at the rear side thereof, the two are symmetrically disposed with respect to the handle of the club, so that the balance of the latter is not disturbed. This is a point of much importance. Furthermore, by securing the segments together removably, other segments of varying weight may be substituted readily at the whim ofv the J A player. If in the use of the club, the dimensions of the weights or the head change due to shrinkage etc,, then'the weight (Z may be threaded fartherpnto the stud 0 so as to take up any'looseness in the parts. 4

Themodified construction shown in Fig. Sdifi'ers from the construction shown in Fig. 2 in that the stud ct by which the two weights are connected is formed integral with the rear weight d instead of with the striking weight 0. Under difi'erent conditions of use one arrangement may be found more desirable than the other or it may be that the cost of manufacture will' make it .edesirable to employ one construction rather than the other. I

I claim as my invention:

1." In combination with a head, a face plate a weight disposed in therear face of said head, and traction means operably eon- 'necting said face plate and said weight.

2. In combination with a head, face plate, a weight disposed in the rear face of said head, and traction means comprising a shank rigidly fastened to the one, and held in threaded engagement with the other.

3. In combination with a head, a face plate, a weight disposed in the rear face of said head, and means connecting said weight with said face plate, so that a rotary movement imparted to said weight will draw said face plate toward said head.
